>Can someone advise why when I attempt to use the CDONTS email handler I get a message that the class cannot be found? I am running NT Server with IIS. Is there a separate installation that has to be done to enable CDO?

I believe there is a separate "Internet Mail Service" setup. Read about it here: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cdo/html/_denali_installing_cdo_for_nts.asp?frame=true
